Book Description
The Energy Policy Act of 1992 required NHTSA to conduct a study of the safety impact of permitting right and left turns on red lights. The report presents a brief summary of the current status of State implementation of laws permitting right and left turns at red lights, a brief review of previous research, and the results of analyses of currently available data assessing the safety impact of permitting right turns on red.

Book Description
"The purpose of this study was to determine current motorist compliance to RTOR regulations, develop and field test countermeasures for RTOR pedestrian accidents, and develop improved warrants and guidelines for prohibition of RTOR. Based on data from several U.S. cities, only 3.7 percent of all right-turning drivers violate no turn on red (NTOR) signs. However, of drivers with an opportunity to turn right on red, 20 percent violated the sign. At locations with RTOR allowed, 56.9 percent of motorists do not come to a complete stop before turning right on red. Based on conflict and violation data, 30 countermeasures were developed as possible treatments for RTOR-pedestrian accidents. Seven of these were field tested, including an offset stop bar, a red ball (symbolic) NTOR sign, a larger 30x36-in (75x90-cm) NTOR sign, a Look For Turning Vehicles pavement marking, a NTOR When Pedestrians Are Present sign, and an electronic variable message (blank-out) NTOR sign. Several promising applications for the devices were recommended. A critique was made of the current MUTCD guidelines on RTOR prohibition. Based on an analysis of conflicts at 199 intersection approaches, improved guidelines were recommended"--Technical report documentation page

Book Description
The Commonwealth of Virginia implemented the sign permissive or "eastern" rule permitting right turns on red traffic signals where designated by sign in 1972. In 1975, as a result of the growing national trend toward employing the general permissive or "western" rule (right turn on red permitted except where prohibited by sign) and in the interests of motor fuel economy, the Virginia General Assembly directed the Department of Highways and Transportation and the Highway Safety Division to study right turn on red (RTOR) to determine whether Virginia's sign permissive law "should be retained, rescinded, or amended." The scope of this study included a survey of the literature, a survey questionnaire of Virginia traffic engineers, a telephone survey of traffic engineers in other states, field studies of vehicle delay times and traffic conflicts at 20 selected intersections in Virginia and North Carolina, and an analysis of traffic crashes at 20 intersections in Virginia before and after RTOR was permitted. The results of this study reveal that right turn on red signals can enable motorists to effect substantial savings in time and concomitant savings in gasoline by reducing the vehicle idling time at intersections. The average saving for right turning delayed vehicles was found to be 14 seconds. Since the general permissive rule for RTOR allows the maneuver at a greater percentage of approach legs than does the sign permissive rule, time and energy savings have been estimated to be greater statewide under the general permissive rule. Estimated savings in gasoline under the general permissive rule would be over three million gallons annually. No significant increase in traffic crashes was found in Virginia and no increase would be expected with the general permissive rule, as none has been experienced in any other state with either the general permissive or the sign permissive rule. Moreover, study data reveal that traffic conflicts and thereby crash potential are actually reduced under RTOR, and that crashes which do occur because of RTOR are generally not severe. When the total impact of RTOR was considered, the evidence was found to support the recommendation that Virginia implement the general permissive rule for right turn on red.
